Java 中error: non-static variable count cannot be referenced from a static context 大多数时候,当我们尝试在 main 方法中使用非静态成员变量时,会出现error: non-static variable count cannot be referenced from a static context错误,因为main()方法是静态的并且是自动调用的。 我们不需要创建一个对象来调用m...
可以的。类可以有内部类，具体问题。具体再追问。错误提示是说：非静态变量类型不能在静态上下文中引用。（1）你的；main方法是static的，即静态的。（2）如果你将类包含在里面的话，需要将printchar声明为静态的。才能在main方法中引用。首先楼上说的有歧义，如果在static方法中new 一个对象都不行的...
“Non-Static Variable … Cannot Be Referenced From a Static Context”当编译器尝试从静态方法访问非静态变量时,就会发生此错误: public...intcount=0; public staticvoid main(Stringargs[]) throws IOException { count++;//compiler error: non-static...variable count cannotbe referenced from a static co...
Capabilities: Unlike static methods which cannot access non-static variables and methods, these methods can access both instance variables and static variables. Instance Methods Example classMyClass{ // non-static variable intinstanceVariable=20; ...
class MyCar { int tyres = 4; //non static variable public static void main(String[] args) //static method { System.out.println(tyres); } } When you run this program, you will get: In the given code, "tyres" is an instance variable, and it is being accessed from a static method...

Static variable retains its value while non-static or dynamic variable is initialized to '1' every time the function is called. Hope that helps. reference: http://stackoverflow.com/questions/5255954/what-is-the-difference-between-static-and-normal-variables-in-c...
A static variable is common to all the instances (or objects) of the class because it is a class level variable. In other words you can say that only a single copy of static variable is created and shared among all the instances of the class. Memory allo
Likestatic methods, a static variable belongs to the class itself, and a non-static variable belongs to each instance of a class. Therefore, the value of a static variable remains the same for each instance of the class, but the same cannot be said for the non-static variable. We cannot...
